This is really cute under a jean jacket or even dressed up with any jacket. The brand is "I love you" I see no size tag. It fits like a small. Approx 13i 1/2 in width at bust.approx 14 1/2 length. has a cute metal design that reminds me of a belt buckle. Cute, stretchy. From what I can tell this is either a rayon spandex blend or polyester span blend but not sure. pre loved but still alive and vibrant
